of operative adjustment on the part of the operator. Y

1t isV extremely important, to avoid serious injury to the shoesoperated upon, that theY machine be constructed to afford invariablyeffective support for the portions of the shoe sole being treatedagainst the thrust of the indenting tool. At the same time, the machinemus't be constructed so that the indenting tool may be readily projectedinto the angle between the upper and the sole margin under theoverhanging Yportion of the upper far enough to .carry the indentationsclose to the junction of the upper with the sole margin Without dangerof forcing the upper and sole apart so as to Vdistort the sole andinjuriously open up the crease be tween the upper and the sole, therebyWeakening or breaking the sole or Welt attaching 'seam and seriouslydamaging or entirely crippling the shoes and renderingl them un salable.

An object of the present invention is to provide a machine adapted forperforming both the indenting and the edge finishing operations at thesame time which will be so constructed and arranged that a propersupport will be provided for the portions of the shoe sole beingoperated upon against the thrust of the indenting tool, Whatevermanipulation of the shoe may be desirable to secure proper indentingand'indentation burnishing according to the requirements of anyparticular shoe or type of shoe, and which will at the same time besoorganized that, Whatever the requirements of the particular shoe orWhatever manipulation of that shoe is necessary, the indenting and edgefinishing operations may be properlycarried on simultaneously ifdesired.

in accordance with important features of the invention, in theillustrated machine, the shoe sole is supported unyieldingly against thethrust of the indenting tool bya Work support or abutment which, asshown, permits the solo to be rocked into different angular relations tothc' indenting toolvvvhile always supporting the portion of the solebeing operated upon unyieldingly against the thrust of the indentingtool in any angular position of the sole relatively to the tool. ln theillustrated construction, the Work support is a abutment constructed andarranged to engage the corner formed hy Y the junction of the verticaledge and tread faces of the sole, which abutment is apart of the edgesetting tool. Y. It is further of importance that the invdenting andedge setting instrumentalities this invention to organize theinstrumentalities of the machine so as to satisfy these requirementscompletely, and important features of the invention consist inv aconstruction and arrangement of the indenting and edge setting toolssuch that they may be moved relatively to each other vabout the cornerformed by the junction of the upper and vertical edge surfaces of thesole as a center. As shown, this center lies substantially in theintersection of the working faces of the indenting and edge settingtools. In accordance with another feature of the invention, theVillustrated construction and arrangement are such that one of the toolsis adjustable toward the center about which the relative angularadjustment of the tools is effected, so that a close relative'adjustment of the tools can be made and preserved while altering theangle between them.

Another serious diiiiculty encountered in the use'of machines usingheated tools profiled to correspond to the surfaces they are to treat,as such machines haveV been constructed heretofore, has arisen from` thenecessity of changing the tools frequently in accordance Ywith changesin the styles of the shoes operated upon. The high operativetemperatures of the tools make them so diliicult to handle that it hascome to he the practice to mount them somewhat loosely in the machines'so that their removal does not oblige the Voperator to grasp them veryfirmly or to hold them very long. This expedient not only does noteliminate the danger of injury to the operator, but the looseness of thetool mounting causes wear and consequent loss of adjustment or inferiorwork.

Moreover, in some classes of work, vfor example, where it is importantto give independent and especial consideration to the indenting and edgesetting operations, the shoemay be treated twice; the shoe beingmanipulated in the lirst operation primarily to secure the desiredrelation of the indenttakes the vertical edge of the sole more or less'.out of contact with the profiled face of the iron, and subsequently in asecond operation, reversely, the operatormay manipulate theshoeprimarily with a'view to insuring proper treatment of the verticaledge face of the sole by the edge setting iron, more or less withoutregard to the position of the indenting tool. It is sometimes desir d,however, to perform the edge setting operation separately from theindenting operation. Y

It is a further object of this invention to provide a tool mountingwhich shall hold the tool firmly and yet provide for the ready removalof the tool. Another feature of the invention consists in the provisionof means for readily ejecting the tool from the-niachine without contactby the operator. This not only eliminates all danger of injury to theoperator but, at the same time, the suhstitution of a cold iron or ablank iron for the heated profile iron is facilitated whenl ever it isdesired to indent without settng the edge.

In accordance with a further feature of the invention, the illustratedmachine is so organized that one of the tools may be withdrawn toinoperative position whenever desired without loss of cooperativeadjustment, so that the withdrawn tool can be readily replaced incooperative relation to the other tool without loss of time.

Another important feature of the invention consists in a novelconstruction of edge setting iron having a shank of polygonal .aburnishing machine in which my invention has been incorporated,

The head 10 carries the shaft 1l which is rapidly oscillated bymechanism. notshcmfn,V

Bolted upon the end of the shaft 11 is the tool carrying head 12. Thehead 12 has an arcuate slot 13 formed in one side in which slides acorresponding arcuate boss 1/1 formed on the inner surface of one of twospaced plates 15. rlhe plates 15 have rack teeth 16 at their rear endsarranged on an arc of a circle concentric with the arcuate boss 14. Sideplates 17 are bolted to the head 12 outside the plates 15 by transversebolts 18 extending through them and the head 12. A pinion 19 mounted inthe plates 17, meshes with the rack teethv 16 and is operated by the,knurled head 20. The forward bolt 18 passes through the plates 17 andan arcuate slot 21 in the plates 15 which are rigidly connect-edtogether in any suitable manner as by a rib 15', and may be rotatedabout the center of curvature of the rack 16 by turning the knurled head20. As will be shown later this center is substantially in theintersection of the working faces of the indenting wheel and theburnishing iron.

In the spaces between the edges of the plates 15 which project beyondthe edges of the head 12 are mounted the stitch indenting wheel carrier22 and the edge setting iron The carrier 22 is slidably mounted againstthe rib 15 between the plates 15 and has mounted upon it a screw 24Cwhich extends through a hole in a plate 25 mounted upon the top edges ofthe plates 15. The nut 26 adjusts the screw, and consequently thecarrier 22, longitudinally between the plates 15 against the tension ofa spring 27, one end of which rests against the carrier and the otheragainst the plate 25.v The carrier has a notch 28 in which a tooth 29 ona spring 30 is adapted to engage when the screw 24 is drawn back to itsutmost extent (as may be done by graspthe nut 26 with the fingers), thusholding the carrier 22 and the stitch indenting wheel 31 retracted outof operative position, when itis desired to dispense with it and to usethe iron 23 alone, or to remove the iron 23 in order to change it or todispense with it, as will be described. The unscrewing of the nut 26permits the removal of the carrier 22 when it is desired to change thewheel.

The combined edge setting iron and sup- .port 23 is rectangular in crosssection and fits closely into the rectangular space between the squarelower edge of the head '12 and the lower projecting edges of the plates15. It is thus firmly supported against lateral vibration and againstthe tendency to rotate about its longitudinal aXis. It is supported withabsolute rigidity against longitudinal thrust by a rod or plunger 32which acts as an abutment slidably mounted in bosses 33 and 38 on thehead 12. This rod carries a pinned cellar 34 between which and the boss33 is mounted a spring 35 which holds the collar against the sleeve orabutment 36v which will ,be described below. A spring 32, mounted on theboss 33, engages the rear side of a notch 33', holding the iron firmlyagainst the head 12 and the rod 32. yA blow upon the projecting rear endof the rod 32 will drive it forward against the spring 35 andfcause itto knock the iron 23 forward past, the spring 32, and out of themachine, the wheel 31 being previously drawn back out of the way asabove described. It is clear that a hot iron can be removed quickly butwithout the necessity of touching it with the fingers, thus avoidinginjury to the operator and permitting a tighter, firmer mounting of theiron than has been heretofore used in this type of machine. A new ironmay be inserted by placing it between the projecting edges of the plates15 and pushing it backward until the spring 32 seats in the notch 33.

In accordance with an important feature of the invention, intheillustrated machine, the iron itself is used'as an abutment orsupport for the shoe against the pressure of the wheel 31. The iron hasof course the usual bed 332 and channel guard 333. The shoe, beforepresentation to this machine,has already been trimmed by a cuttercorresponding exactly in contour to the formed surface of the iron, Yandthe sole, therefore, fits snugly against the bed 332 and channel guard333. The beveledy portion 33t-of the channel guardy and the bed 332 forma notch into which the corresponding corner at the bottom of the soleedge fits. The beveled portion 334c of the channel guard'and the back335 (at points on the sole edge where the sole is thick enough to reachtothe back) support the lower corner of the sole and buttress the soleextension irmly'against the pressure of the wheel 31. This support, inthe machine shown, comes at the Corner, and nowhere else, so that theshoe can be rocked a substantial amount to enable the upper surface ofthe sole edge and the working surface of the wheel 31 to be brought intoeX- actly theA relative position desired, or to insure penetration ofthe wheel to the bottom of the crease, without losing the support. lThebevel 334 and back 335 make acute angles with the working surface of thewheel 31, so that the extension is, in effect, wedged up between thearms of a V having the indenting instrumentality at one side. Thisrelieves the operator ofthe necessity of pulling the shoe against thewheel, and makes for uniform even work without undue exertion on hispart.

lt is of course notindispcnsable that the support for the sole edge be apart of the edge setting iron, since the main advantages of theinvention can be secured by any .drm

support rigid transversely of-the sole edge under the part of the soleedge being treated, against which the edge may be pressed by theindenting tool, thus avoiding any tendency to pull open the seam joiningthe upper to the sole or welt.

The illustrated construction and arrangement are particularly designedkfor wheeling and setting together, the drawing Yshowing a profile edgesetting iron designed to set the edge in conjunction with the wheelingand burnis'hingrof the upper face of the stock. In some uses of themachine, for example, on high grade shoes, such as many welt shoes, itis important to give independent and especial consideration to thewheeling and the setting.k It is particularly important that any givenshoe bermanipulated to insure that the wheel penetrates the crease orangle between the body of the upper and the sole suliiciently to carrythe indentations well under the overhanging upper, With this in view,the wheel and the abutment for the corner of the sole are relativelyconstructed and arranged to permit the shoe to be freely fulcrumed orpivoted about the said abutment to permit the wheel to enter the angleas far as desired, and at the same time to cause the Vwheel properly totreat the upper'face ofthe stock. In some classes of work, for example,where it is desired to wheel the shoe twice, inthe first wheeling theshoe may be manipulated primarily to secure the desired relation of thewheel to the upper face of the stock, regardless of whether or not suchYmanipulation takes the verticaledge of the sole more or less out ofcontact with theprofle face of the iron, and

subsequently in the second 'wheeling re versely, the operator may guideby the iron, taking care that the edge face of the sole is properlyrelated to thev iron for the best possible `edge setting and withoutregard to the position of the wheel. In the former operation untowardresults due to lack of exact correspondencezor fit between the iron andthe sole edge maybe avoided by wheeling the-shoe against a cold iron, oragainst a blank iron; The substitution of a blank` -iron for theyprofile edge setting iron is greatly facilitated by the describedconstruction and arrangement providing'means for instantaneouslyejecting an iron from the v machine without contact by the operator andconsequently without danger of burning the operators fingers.

The collar 34 rests against a yknurledV sleeve 36 on the rod 32', whichhas an eX- ternally threadedV portion`37 screwing into The center ofcurvature cf the rack l@ and the boss 14C is substantially at theintersection of the working face of the wheel 31 with the working faceof the iron 23. When the knurled head 2O is rotated the plates 15carrying the stitch indenting wheel v31 are rotated around this centerso that the angle between the operative surfaces of the wheel 31 and theiron 23 is suitably changed without altering the registration of thesetools relatively to the work. The iron 23 is not mounted upon the plates15 but rests against the lower surface of the head 12 and remainsimmovable while the above-mentioned adjustment is made.

It will be noticed that the operative (the lower) 'surface of the wheel31 is substantially parallel to theaXis of the carrier 22, the journalof the wheel being set up at an angle, so that the operative surface ofthe wheel 31 Vwill remain in contact with the work in whatever positionthe carrier may take in sliding along the rib 15.r It will be obviousthat the adjustment of the wheel 31 Vby means of the nut 26 merely setsan outside limit to the protrusionr of the carrier 22 from the plates 15; Pressure upon c the outside surface of the wheel 3l will force itbackward against the spring v27 So that it may respond to variations inthe width of the upper surface of the sole edge, thereby allowing thesole edge to rest firmly against the iron 23 while the outside surfaceof the wheel 31 rests against the lower edge of the vamp. Gas pipes andburners 10 are arranged to heat the iron 23 and wheel 31.

I have thusprovided an indenting ma: chine in which provision is madefor the firm support of the sole edge under the pressure of theindenting tool andwhich is convenient in use, irrespective of, andrequir-v ing no great exertion on the part of the operator in effecting,the positioning of the shoe necessary in the case of individual shoes tobring the indenting tool into proper relation with the 'sole extensionYand the upper and to cause it to operate to the bottomV of the creasebetween the upper and the upper face of the sole extension.

I have provided an indenting wheel and a .burnishing iron which arerelatively an-` gularly adjustable about a point substantially in theintersection of their working vsurfaces and also Yadjustable toward andfrom this point independently. The latter feature'permits distanceadjustment to take up slight variations in the size of tools, andinsures free interchangeability, while the former feature permitsrelative angular adjustment without loss Vof distance adjustment.
